Does PayPal Pay in 4 have a limit?

I'm curious to know if there's a spending limit associated with PayPal's Pay in 4 service. As a consumer, it's important to understand the financial implications of using this payment option. Is there a maximum amount that can be split into four interest-free payments, or is it more flexible depending on the merchant and the individual's account status? Clarifying this information would help me make more informed decisions when shopping online.
